Never! My favorite way to carry a single spare is an Oveready Delrin capsule. Multiples would be in a storacell.
6PX burned for about 12 more hours and then went out. The old Panasonic showed 0.8V, the new battery 2.6V. I left the flashlight on for those few days. It did not light up, no leaks, the voltage increased to 1.2 and 2.9. I think this is because of the 6PX scheme itself. Malkoff will continue to shine very faintly

Risk, like so much in life is on a scale from not very likely to 100%. The members here have a healthy respect for CR123 batteries. I used to have a few 2 x Cr123 flashlights but got rid of them because I did not want to risk my family's health. None of them are flashlight enthusiasts and therefore the risk would be higher with them than with me. You are here, at CPF so that's a good start.
Lots of people in life use the words "the risk is low" when what they mean is "only some of you will die". Remember that when some talking heads on TV dismiss someone's very real concerns.
If you are pro active about your cells, it is less likely to be a problem. BUT, it has happened before so just be aware of that.
@Toulouse42, @ghostguy6, @Monocrom, @bykfixer <<- and others say very correctly, there is no need to take risks unless you build a special test facility, as described, or do everything in an abandoned quarry. Now there are a huge number of very good single-element flashlights, which are no worse in brightness than many two-element ones. Or the same, but with a little less operating time
What I am checking now is because the risk of fire is too small and insignificant for me compared to what can happen to me every day. Perhaps my sense of danger has become very dull

If your still worried about the dangers of cr123's you should read the ROAR of the Pelican thread. After reading all the pages the only way anyone was able to reliably get an explosion was to either intentionally disable the protection circuit or by mixing 30 to 40 percent depleted cells with new ones. The ambient temperature seemed to come into play as well. If it was too hot the cells would still trip the protection circuit. This is discussed on page 32 of the thread linked above.

Not me, but I do carry a spare CR123A in a pouch in my handbag with other things that are metal. None of them are able to short-circuit the battery, though. Keys and change do not go in that pouch.
I have several single-cell Delrin battery lockers from County Comm (with screw-on Delrin tops) that are ideal for carry in a sling-bag. Should work in a purse. No reason to carry a completely loose cell. The Delrin does start to break down after awhile. Not in physical structure. It just causes itself and the cell in it to stink of rotten fish, if you put it up to your nose. Minor price to pay for the safety and protection the lockers give.
Thanks for the link, very interesting topic. Today I read the whole thread, and ended up ordering an Ansmann tester, I hope it will help sort the batteries by charge level
Just make sure said metal objects cannot puncture the cell in case the bag gets crushed, dropped, sat on, or any other event. My biggest fear is not short circuits, it's puncturing.

Weird, I've never noticed acetal (Delrin) plastics giving off any kind of odor over time. For about 25 years, I swore by a particular brand of acetal guitar picks, so I carried them all the time. A few years ago, I switched to Ultem picks, which have a brighter sound than Delrin.
But, thanks for the tip on the battery cases. I just might get one or two.

Delrin can smell like formaldehyde also
I suspect it's a case of manufacturers experimenting with different formulas in order to produce Delrin more cheaply. Wouldn't be the first case of "Good Enough" syndrome occuring in America.

The delrin capsules are handy investments . I've taken a CPF friends advice and started using the slightly larger Fenix E16 as a spare CR123 holder. I wish Fenix would bring the E16 back... it's a great spare carrier with a excellent low level runtime 
The CR123 is still a great cell for shelf life, runtime and watch pocket portability.

It was mentioned on here about how these batteries are used on power equipment battery packs and batteries. Drills,saws,vacuums and blowers are my devices. I would ask that i have a real old drill that the batteries just would not charge anymore and it was cheaper to buy a new more advanced drill. But after 15-20 years i still have those batteries somewhere? I guess if they were going to explode or catch fire they would have done so a long time ago?
But i should dispose of them? How to when i find them? Lol

Every city has Battery Recycling Centers (obviously more than one).
Use your computer to find out where they are, and you can drop off those old rechargeable batteries at one of the centers. Definitely dispose of them once you've located them. Just because something has been well-behaved for many long years, doesn't mean it always will be. No reason to take unnecessary risks. Get rid of them.

Good advice. Can't be too safe.
Okay, I asked the SF a question, they were extremely kind and sent me the safety data sheet
I assume the smell during normal use and storage is one or both of these solvents. So far I have found that the first solvent has a slight fruity smell and is used in cosmetics and can cause eye irritation in high concentrations. The second one already affects the lungs, causes suffocation and has an ethereal smell
